Application filed July 6. 1905-. Serial No. 268,326.

To all whom it may concern:

Fig 9 is a perspective view of the instrument Be it known that I, CLAUDE EARLY FIELD, 1 employed for drawing the wire throughthe a citizen of the United States, and a resident spacing-blocks. Fig. is a perspective of of Slater, in the county of Saline and State of the bale-tie employed, and Fig. 11 is aperspec Missouri, have invented a new and Improved Baling-Press, of which the following is a full, clear, and exact description.

My invention relates to presses for baling hay, straw, and like material.

The purpose of the invention is to provide a construction of press in not employed and wherein the feed mechanism is such that the press can be fed at any time while in operation, it not being necessary to await the return of the plunger, as required in all the baling presses of which I have knowledge.

Another purpose of the invention is to provide a construction of baling-press in which the power is utilized at all times during its operation and wherein the feed iscontinuous, thus dispensing with the violent back stroke of a plunger, which tends to rapidly wear out and rack the machine.

A further purpose of the invention is to im prove upon the formation of the spacingblocks and to provide positive means for feeding them and the bales out from the ma- I chine and also to provide simple and effective means for wiring the bales and securing the wire on the bales.

The invention consists in the novel con struction and combination of the several parts, as will be hereinafter fully set forth, and pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts inall the fig.

ures.

Figure 1 is a side elevation of the improved press. Fig. 2 is a plan view of the same. Fig. 3 is an enlarged longitudinal vertical section through the forward portion of the press, the section being taken practically on the line 3 3 of Fig. 4. Fig. 4 is an enlarged vertical transverse section taken substantially on the line 4 4 of Fig. 1. Fig. 5 is a horizontal section taken substantially on the line 5 5 of Fig. 3. Fig. 6 is a detail horizontal section taken practically on the line 6 6 of Fig. 3. Fig. 7 is a detail transverse section through one set of bale-feeding arms and a dog carried thereby. Fig. 8 is a diagrammatic view illustrating the manner in which the tie-Wire for the bales is manipulated.

which a plunger is tive view of a modified form of spacingblocks. I

The body A of the press is carried by a truck B. In the construction of said truck the rear axle 10 is provided with supportingwheels 11 and a bolster 12, having a longitudinal recess 12 in its upper surface. The forward axle 13 is provided with smaller wheels 132atongue or pole 14, anda bolster 15. The construction of the truck is completedby securing. side beams 16- to the upper portion of the bolsters at their outer ends:

and attaching: transverse sleepers 17 to the beams 16. The sleepers 17 are placed at predetermined intervals apart and are of greatest depth at their central portions. The body A- rests upon and issuitably attached to thesleepers 17, as is showninFig. 1

That portion of the body containing the} baling-charnber A is made in two sections, an upper section 18 and a lower section 19, and at the forward portion of the balingchamber A the sides of the sections-1'8 and 19 are brought sufficiently close together to form centrally-located longitudinal side slots 20 which connect at their forward ends with upwardly and forwardly inclined slots 21. Said slots 21 extend out through the body its entire Width at the top, as is also shown in Fig. 1. The extreme rear portion of the body A is in the form of an open horizontal plat form 22, which constitutes a continuation of the floor of the baling-chamber A, while between the inner end of the platform 22 and the rear end of that portion of the body 0011-. taining the slot 20 the-sides of the body are cut away, so as to expose a sufiicient surface of the bales to enable them to be tied.- The two sections 18 and 19 of the body are connected in any approved manneras, for example, by securing transverse battens 23 on the top of the said body and connecting these battens with the sleepers 17 by means of rods 24.

The feed-chamber A is at the forward end of the body A and is in direct communication with the baling-chamber A. The upper portion 25 of the feed-chamber A is-open and surrounded by a hopper 26, as is shown in Fig. 3. Parallel longitudinal slots 27 are made in the bottom of the feed-chamber and the forward portion of the bailing-chamber to accommodate feed-fingers to be hereinafter described, and said parts are normally covered bya sheet 28, of rubber or other flexible elastic material, as is shown in Figs. 3, 4,

and 5. l

Below the forward portion of the body A a rear shaft 29 and a forward shaft 30 are journaled in bearings located on the beams 16, the bearings being designated, respectively, as 29 and 30 and sprocketwheels 31 are secured on the shaft 29, one near each end, while corresponding sprocket-wheels 32 are secured upon the shaft 30. The two shafts 29 and 30 are parallel, and chain belts 33 are passed over corresponding sprocketwheels 31 and 32. These chain belts carry feed-fingers O, above referred to. These feed-fingers C are arranged in pairs and are located adjacent to the inner edges of the said feed-belts, occupying such a position that as the belts 33 revolve the fingers extend u through the slots 27 in'the bottom of the feed-cnamber A as is shown also in Fig. 3.

- A longitudinal guide-block 34 is located about midway between the belts 33, as is shown in Figs. 3, 4, and 6, the said guideblock being supported by a cross-bar 35, car ried from one beam 16 to the other. The feed-fingers. C are of angular formation, com prising a long member 0 and a short member 0, the short member being at right angles to the long member, as is best shown in Fig. 3. The feed-fingers of a pair are placed one parellel with the other, and pins 36 are passed through eyes formed at the junction of the members of the said fingers. The said pins 36 are secured in any suitable or approved manner to the chain belts 33, as is shown in Fig. 3, and rollers 37 are mounted on the said pins 36, turning loosely between the feed fingers.

At the outer end of the shorter members 0 of the feed-fingers 0 eyes are formed, and pins 38 are passed through said eyes. On these pins 38 rollers 39 are mounted to loosely turn between the feed-fingers, the rollers 39 corresponding to the rollers 37. These rollers in the operation of the belts 33 engage with the marginal portions of the guide-block 34. This guide-block is of peculiar construction, and its construction is best shown in Fig. 3, wherein it will be observed that the top a of the block is straight, the upper rear corner a is rounded, the rear end portion a is straight, and the bottom a is likewise straight from the rear end of the block to an angular recess (1 made in the bottom forward portion of the said block, and the forward end of this reduced portion of the block is curved upward to meet the straight upper surface a, as shown at cf, the curvature at the bottom being much sharper than'the curve leading directly to the upper edge.

The shaft 29 is provided with a pulley 40 for belt connection with a motor, and said shaft is also provided with a polygonal end section 40, so that horse-power may be employed, if desired. As the shaft 29 is rotated motion is imparted to the belts 33, which belts move in such direction as to cause the uppermost feed-finger C to travel rearward. W hen the fingers are-in their upper position, the larger members 0 extend up into the feedchamber A through the slots 27, forcing the cover-strip 28 to one side as they travel along, as is shown in Figs. 3, 4, and 5, and the fingers C must thus force the material from the feed chamber into the baling-chamber, as both rollers 37 and 39 of thepair of fingers will be in contact with the upper straight edge a of the guide-block 34.

As the upper stretches of the chain belts 33 move forward the roller 39 will move on the guide-block at its rounded rear corner (1 whereupon the straw or hay will give the members 0 of the fingers C a forward inclination, and as the pivoted portions of the fingers are carried downward the members 0 will gradually straighten, since said members will be brought against the rear end walls of the slots 27 but the moment the said members c of the fingers C clear the slots 27 said members 0 will drop downward and assume the lower position shown in Fig. 3. hen the members 0 of the fingers O strike the lower edge of the recess 12 in the bolster 12, the members 0 will be brought to a substantially vertical position, the rollers 39 then being in engagement with the lower edge 0. of the guide-block 34. When the recess a is reached, the members 0 can drop, and as the belts rise at the front of the machine the rollers 39 of the short members 0 engage with and ride upon the forward curved under surface a of the guide-block, bringing the members c of the fingers once more to the vertical position at the top of the guide-block, also causing the said members 0 to enter the slots 27, take up the material in the feed-chamber A and pass it into the baling-chamber A. In order that the fingers C may readily rise at the front portion of the machine, the forward sleeper 17 is provided with a concaved recess 40' upon its inner face, as is shown in Fig. 3.

D represents a spacing block or board which conforms to the shape of the balingchamber A, but is of such dimensions as to have free sliding movement in said chamber. The spacing-block is provided at top and bottom with a groove 41, and a wall at one side of each groove is deeper than the wall at the opposite side. The shorter wall is at the front portion of the block at the top and the rear portion of the block at the rear of the machine, for example, as is illustrated in Fig. 3. The block D isprovided with trunnions 42, centrally located in its side surfaces, and these trunnions extend out through the slots 20 when the board is in place in the said baling-chamber A. A spacing board or block D is introduced into the baling-chamber whenever'sufficient material has been fed thereto to make a bale and when introduced the trunnions 42 are made to enter the inclined extensions21 of the horizontal slots 20.

InFig. 1 1 I have illustrated a modified form of the division board or block, (designated as D This block is reduced in width at the bottom, forming heads 44, and each head is provided with a roove 45, extending from one side of the b loc'k to the other. These grooves receive the lower flanged portions of sliding caps 46, which caps are of such size that while they are flush with the side faces of the blocks they extend, respectively, beyond the upper and lower faces of the heads 44, so as to provide a space through which the wire is to be drawn. baling-Chamber A has been divided into bales by the introduction of the division boards or blocks D it is desirable that the bales and boards be automatically discharged from the said chamber A, and this is accomplished by a pressing mechanism especially designed for the purpose and which is particularly shown in Figs. 1, 2, 4, and 7. This mechanism is as follows: Two sets of feedbars 47 and 48 are placed in parallelism, one in front of the other at each-side of the body A, extending from a point near the forward end to the rear of the slots 20, practically in registry with the lower walls of said slots, as is shown in Fig. 1. Each pair of arms at their forward ends are provided with longitudinal slots 49 and at their rear ends withcorresponding slots 50. These feed-bars 47 and 48 have simultaneous sliding movement in opposite directions, and their movements are limited by check-screws 51 and 52 or their'equivalentsas, for example, sheaved rollers on screws or pinsthe screws 51 being passed through the slots 49 and the screws52 through .the slots 50,all the screws entering the body A. A press-b ar of each pair 47 and 48 is provided with two parallel downwardlyextending contact-arms, the arms of the bars 47 being designated as 47 and the arms of the bars 48 as 48*. A series of dogs 53 of angular formation are pivoted between the press-bars of each pair, their head portions being normally upwardly and rearwardly inclined, as is shown in Fig. 1, and as the feedbars 47 and 48 move rearward the most convenient dogs 53 will engage with a trunnion of a spacing-block D, causing said block, and consequently the bale against which it bears, to be given a movement in direction of the platform 22 at the rear of the machine. At the rearward movement of the said bars 47 and 48 the dogs 53 are held in positive position for engagement with the trunnions 42 of the spacing-blocks D by means of stoppins 54, which engage the dogs below their pivots, as is shown in Figs 1 and 7'; but when the After the material in the said press-bars 47 and 48 are on their return or forward stroke their head portions simply slip by the trunnions 42 of the spacingblocks D, having no action upon them and 1 being uninterrupted in such action by said stop-pins 54, which only act as specified.

The necessary movements are imparted to the press-b ars 47 and 48 by securing cams 5 5 and 56 on the shaft 29 near each end, the lengthy portions of the cams extending in op posite directions, as is shown in Fig. 6. These cams are necessarily placed close together at each end of the shaft, and the cam 55 operates between the contact-arms 47 a of the press-bars 47, while the cams 56 operate between the contact-arms 48 of the pressa bars 48. Under this arrangement as the shaft 29 is revolved the cams simultaneously act to carry one pair of press-bars at each side of the machine rearwardly for action. After the bales have been formed in the balin -chamber A it is necessary to wire the said bales, and this wiring process is carried out while the bales'yet remain in the balingchamber and when they have reached the open side portions of said chamber, as is particularly shown in Fig. 1. lefthand side of the body at a point to. the rear of its open side portions, two reels 57 and 58 are mounted to turn, the said reels carrying the tie-wire 59. These wires 59 are led from a reel through suitable guide-staples 60 or their equivalent to the said open portion at the left-hand side of the body.

In wiring a bale an instrument E is employed. (Shown particularly in Fig. 9.) This instrument consists of a bar-body 61, preferably made flat and rectangular in cross-section, being pointed at one end and provided at the other end with an offset 62 at right angles to the body proper, and the said bar-body 61 is likewise provided with a substantially V-shaped recess 63, produced in its upper edge adjacent to the point, and between the point and the said recess 63 a clamping-finger 64 is pivoted to the bar body, the clamping-finger having a recess 65 in its head or free portion and a semicircular recess 66 in its under face adjacent to the head. The clamping-finger 64 is pivotally connected to one end of a rod 67, and this rod has free movement in the offset 62 and terminates in a suitable knob or handle 68. Upon drawing the rod 67 outward or away from the point of the bar-body the clampingfinger is drawn downward over the recess 63, and the wire strand or wire which may have been passed over the lower portion of the clamping-finger in its lower position, as the said finger straddles the bar-body to a greater or lesser extent. When the wire is thus caught and held, it can be mani ulated very readily and quickly released when desirable. This wire-drawer is made of such said recess 63 will be held firmly by the- Preferably at the .two ends of the wire dimensions that it can readily pass through the grooves 41 at the upper and lower portions of the spacing-blocks D and likewise through the upper and lower spaces provided for its reception in the form of spacing-block D. (Illustrated in Fig. 1.1.) After the wire has been properly passed around a bale its ends are connected by means of a bale-tie F. (Shown in detail in Fig. 10.) made of soft metal, such as iron or brass, for example, has flat side faces 69, and may be of any desired length and breadth, but is of greater length than width. Two cuts and 71 are made in the lower edge of the body, diverging from a central point, and the cuts extend diagonally in direction of opposite corners, forming thereby two bills 72 and 73, which are initially bent outward beyond the plane of one side of the body, and in the edges of each cut opposing concaved reci- The tie is sions are made to receive the loose wire and i hold it. In the application of this tie the two ends of the wire are received in the spaces where the bills join the body at the cuts 70 and 71. Then by meansof a suit able instrument the bills are brought into the plane of the sides of the body, thereby clamping the wire. In order to insure a positive grip upon the wire, the bills are forced upon that portion of the body above them, as is shown in Fig. 1.

When the baling operation has been commenced, enough wire is reeled off to permit the wire to be bent upon itself and to pass through the open portion of the balingchamber to and beyond its right-hand side, whereupon the end of the wire is bent, as is shown at b to the left in Fig. 8. As the rear end of the first bale is received in the loops thus formed in the wires 59 the wires are reeled off until the spacing-block D at the forward end of the bale reaches the open space in the side of the baling-chamber, whereupon the instrument E (shown in Fig. 8) is passed, for example, through the upper groove 41 in the said block, and the wire is gripped by the j aw or clamping-finger 64 of the said instrument, as is shown in Fig. 2. The wire is then drawn through the said up per groove 41 to the righthand side of the press, as is shown to the left in Fig. 8, and enough wire is then drawn through to extend some distance beyond the side of the bale. The wire is next cut whereit is gripped by the instrument, and the forward strand is then bent, as shown at b, to receive the next bale, while the rear portion of the cut wire is bent to meet the first or rear are then brought together and secured by the tie F in the manner which has been described. The operation of the instrument E is then repeated at the bottom groove in the spacing-block. When a spacing-block is to be removed from the bale, the wire will readily slip over the bend, and the i a I l l Patent short wall of the lower groove, for example, whereupon the longer wall at the upper groove in the said block can be readily worked out through the wire.

In Fig. 1 I have illustrated an inclined platform G, independent of the press and located at the rear thereof, which platform receives the completed bales from the machine-platform 22. The platform G may lead to a vehicle in which the bales are to be placed.

I desire it understood that I do not restrict myself to the use of the fingers C in pairs, as they may be used singly or in groups of'any desired number. 7
